Question
Indicate those of the following statements that are correct for a liquid consisting purely of the compound 13CH3OH
The carbon-13 spectrum will be a 1:2:1 triplet.
The proton NMR spectrum will be a 1:1 doublet and a broad singlet.
The broad singlet in the proton spectrum is due to the exchange of protons among methanol molecules.
Because of the oxygen, the IR spectrum will have a strong band around 1750 cm–1.
This compound will absorb in the visible region, and will therefore be coloured.
The mass spectrum should have a peak at mass 15.
